13+12 V TRIGGER OUT : There are three configurable +12V TRIGGER OUTPUT. Use a 3.5mm mini-jack connector to pass +12 volts at a maximum current of 50 milliamps to auxiliary equipment such as a multichannel amplifier or subwoofer. The center conductor (hot) of the 3.5mm jack is the control signal. The outside conductor (shield) is the ground return-path.
TRIGGER IN accepts 12V Trigger output of compatible components such as power controllers and home automation devices.
TRIGGER OFF/AUTO. When at AUTO position, the T 765 selects the 12V Trigger Input to turn ON (if so assigned at the ‘Trigger Setup’ menu) and at the same time disables the HTR 3 and front panel’s ON/OFF function. When at OFF position, the trigger input is disabled.
Warning
16AUDIO PRE-OUT :The Audio PRE- OUT makes it possible to use the T 765 as a pre-amplifier to external power amplifiers for some or all channels. Connect FRONT L, FRONT R, CENTER, SURR R, SURR L, SURR- BL, SURR-BR and CENTER to the respective channel input of a power amplifier or amplifiers driving the corresponding applicable speakers.
Unlike the full range channels, there is no power amplifier built-into the T 765 for a subwoofer. Connect the SUBW 1 or SUBW 2 output or both to powered (“active”) subwoofers or to power amplifier channels driving a passive system.
Note
Never connect both the external amplifier and T 765’s speaker outputs to the same set of speakers.

If Auto Trigger IN at Trigger Setup menu is assigned to ‘Main’ or ‘All’ and the TRIGGER switch is set to ‘AUTO’ mode, the Power button in the front panel as well as the corresponding ON/OFF function keys in the HTR 3 remote control will be disabled effectively handing this function to an external controller. Switch TRIGGER to ‘OFF’ to maintain normal power ON/OFF function procedures.
See discussion on ‘Trigger Setup’ at the ‘Setup Menu’ literature for guidelines on how to configure TRIGGER IN/OUT.
14IR IN/OUT : These mini-jacks accept and output remote-controlled codes in electrical format, using industry-standard protocols, for use with “IR-repeater” and multi-room systems and related technologies.
IR IN. This input is connected to the output of an IR (infrared) repeater (Xantech or similar) or the IR output of another component to allow control of the T 765 from a remote location.
IR OUT 2. When connected to the IR IN of an ancillary equipment, direct the ancillary equipment’s own remote control to the T 765’s infrared receiver to command or control the linked unit.
IR IN and IR OUT 3. Connect the T 765’s IR IN to the IR OUT of an ancillary equipment. Connect also the T 765’s IR OUT 3 to another equipment with IR IN feature. With this setup, the T 765 acts as an “IR- repeater” allowing the equipment connected to the T 765’ s IR IN control or command of the other equipment linked to the T 765’s IR OUT 3.
IR OUT 1. In conjunction with IR IN, IR OUT 1 can be used as an “IR- repeater” just like the IR OUT 3 as described above. It can also stand alone as an IR OUT similar to that of IR OUT 2 function.
All NAD products with IR IN/IR OUT features are fully compatible with the T 765. For non-NAD models, please check with your other product’s service specialists as to their compatibility to the T 765’s IR features.
15ZONE 2, ZONE 3, ZONE 4 : Sends zone selected audio and video output sources to the corresponding audio and video input of another separate zone. Use high quality patch cables to reduce noise pickup over long distance runs. For a better understanding of zone settings, study below the section on ‘Zone Controls’ of the ‘Main Menu’ discussion as well as the item on ‘Zone Setup’ under the ‘Setup Menu’ literatures.
Note
The ZR 4 remote control will only control Zone 2 applications. Zone 3 and Zone 4 could be configured and managed at the appropriate Zone OSD menu using the front panel navigations buttons as well as the corresponding keys on the HTR 3 remote control.
17SPEAKERS A, SPEAKERS B : Connect the respective SPEAKER A’s FRONT L, FRONT R, CENTER, SURR R, SURR L, SURR-BL, SURR-BR and CENTER channels to their corresponding loudspeakers. Make sure the “+” (red) terminal and “-“(black) terminal are connected to the corresponding “+” and “-“terminals of the loudspeaker. Use extra care to ensure that no stray wires or strands cross between posts or terminals at either end.
Connect left and right channels of Speakers B to the corresponding remote loudspeakers. When Speakers B is activated, the output is converted to ‘Stereo Downmix’ as indicated in the VFD. Combining Speaker A and Speaker B (SPEAKERS A + B) will also result to the source being downmixed to stereo.
The T 765 is designed to produce optimum sound quality when connected to speakers with impedances within its operating range. Please make sure that all the speakers are rated 4Ω minimum per speaker.
Note
Use stranded wire of at least 16 gauge (AWG). Connections to the T 765 can be made with banana plugs (US model only) or by using bare wire or pins. Use the transverse hole through the post for bare-wire or pin connections. By loosening the terminal’s plastic nut, make a clean, neat connection and re-tighten carefully. To minimize the danger of short- circuit, ensure that only 1/2-inch of exposed wire or pin is employed when connecting.
18AC POWER INLET : Connect to the supplied IEC-standard removable AC power cord or a compatible cord.
19SWITCHED AC OUTLET : This convenience outlet can supply switched power to another component or accessory. It is powered ON and OFF by the front panel POWER SWITCH or by the HTR 3’s ON and OFF keys.
The total draw of all devices connected to this jack must not exceed 120 watts.
20POWER : The POWER switch supplies the master AC mains power for the T 765. When this switch is at ON position, the T 765 is in standby mode as shown by the amber status condition of the standby LED. If you intend not to use the T 765 for long periods of time (such as when on vacation), switch the POWER switch to the OFF position. When the POWER switch is at OFF position, the front panel power button, HTR 3 remote control or ZR 4 cannot activate the T 765.
